Biomass and Bioproduct Characterization

NREL's biomass and bioproduct compositional and structural characterization expertise meets a variety of research, development, and implementation needs for biofuels, materials, and feedstocks.

Our leading-edge analytical tools and techniques enable us to determine the composition and structural architecture of plant cell walls and provide a deep understanding of genetic and environmental impacts on biomass properties, including how it is deconstructed or converted by thermal and biological processes. NREL researchers have expertise in:

• Chemical analyses
• Mass spectrometries
• Nuclear magnetic resonance and other spectroscopies
• Chromatographies and other separations techniques.

In addition, we develop and use standard laboratory analytical protocols, high-throughput screening methods, and novel analytical techniques to advance scientific understanding. Our team has expertise in characterizing thermochemically derived bio-oils and uses a variety of analytical methods and instrumentation to measure the components and properties of these complex mixtures.

Analytical Development and Support

NREL maintains globally accepted laboratory analytical procedures (LAPs) for comprehensive characterization of biomass feedstock, chemically treated process intermediates, and a variety of products relevant to the biofuel and bioproduct economy.

Based on these LAPs, novel techniques and analyses are developed to suit client needs, such as customization to novel feedstocks, focused analysis of key analytes, and method development to meet quality control objectives. NREL has developed rapid analytical techniques capable of at-line or online monitoring of process conversions from bench scale up to industrial production using near-infrared predictive models.

Essential LAPs include:

Biomass compositional analysis

Bio-oil analysis

Microalgae compositional analysis

This project contributes to dissemination of data to industry through direct communication with external researchers regarding the LAP procedures, participation in standards body groups such as ASTM International, and collaboration with industrial partners to tailor the analytical techniques to the specific needs of their processes.

Significance and Impacts

Biomass and bioproduct analysis and structural characterization are foundational to determine, design, and optimize the properties of lignocellulosic biomass and other feedstocks for end-uses in the bioeconomy.
